A new 'two step' procedure for 4.5 log depletion of T and B cells in allogeneic transplantation and of neoplastic cells in autologous transplantation
To evaluate a new 'two step' method for purging T, B and neoplastic cells from hematopoietic progenitor cells (PC), PCs were collected by apheresis and some suspensions were deliberately contaminated with 2-5% breast cancer cells. PCs were first processed through CellPro columns for positive selection of cells that express CD34. After this first step, the mean CD34+ cell recovery was 68 +/- 12%, and CD34+ cell purity was 61 +/- 11%; CD3+ and neoplastic cell depletion were 2.1 +/- 0.4 and 1.9 +/0 0.4 logs, respectively. Cells were further processed through the StemSep device for direct depletion of T and B cells or of breast cancer cells. After the first and the second step, overall CD34+ cell recovery was 50 +/- 7%, T and B cell removal was 4.7 +/- 0.4 log and neoplastic cell purging was 4.4 +/- 0.3 log, ie significantly superior to methods described in the past

Review of Codes and Standards
The chapter deals with a review of the international codes and standard related to the in situ evaluation of timber structures. The ISO 13822:2001 (Bases for design of structures - Assessment of existing structures) standard is the only one at international level on this field, but it's only partially applicable to the topic, because it deals with all the building materials, not only with wood, and because the principal aim is not the conservation criteria, but the structural safety obtained with cost saving. At national level there are two Italian standards the UNI 11119:2004 (Cultural Heritage - wooden artefacts - Load bearing structures of buildings - On site inspections for the diagnosis of timber members) and the UNI 11138:2004 (Cultural heritage - Load bearing structures of buildings - Criteria for the preliminary evaluation, design and execution of works). Both the standards are strictly related to the cultural heritage, then having as first goal the protection and conservation of the artefacts. The main part of the chapter rapidly describes the first of these two standards, aimed to define the mechanical performances of each structural member at the moment of the diagnostic inspection. The steps of the diagnostic path start from the identification of the species, pass through the description of the existing conditions through an accurate constructive survey and the inspection procedures, going finally to the inspection report that describes the result

Nitrous oxide emissions from soil of an African rain forest in Ghana
Recent atmospheric studies have evidenced the imprint of large N2O sources in tropical/subtropical lands. This source might be attributed to agricultural areas as well as to natural humid ecosystems. The uncertainty related to both sources is very high, due to the scarcity of data and low frequency of sampling in tropical studies, especially for the African continent. The principal objective of this work was to quantify the annual budget of N2O emissions in an African tropical rain forest. Soil N2O emissions were measured over 19 months in Ghana, National Park of Ankasa, in uphill and downhill areas, for a total of 119 days of observation. The calculated annual average emission was 2.33 ± 0.20 kg N-N2O ha−1 yr−1, taking into account the proportion of uphill vs. downhill areas, the latter being characterized by lower N2O emissions. N2O fluxes peaked between June and August and were significantly correlated with soil respiration on a daily and monthly basis. No clear correlation was found in the uphill area between N2O fluxes and soil water content or rain, whereas in the downhill area soil water content concurred with soil respiration in determining N2O flux variability. The N2O source strength calculated in this study is very close to those reported for the other two available studies in African rain forests and to the estimated mean derived from worldwide studies in humid tropical forests (2.81 ± 2.02 kg N-N2O ha−1 yr−1)
TRH reverses the ECG and EEG ischemic changes induced by massive hemorrhage in rats
In a rat model of volume-controlled hemorrhagic shock causing the death of all saline-treated animals within 30 min of treatment, the intravenous bolus injection of thyrotropin- releasing hormone tartrate (TRH-T) at the dose of 4 mg/kg induced the prompt and sustained disappearance of the ECG and EEG signs of heart and brain ischemia, along with the reversal of hypotension and respiratory depression and with 100% survival rate at the end of the 2 h observation period. These data confirm that, in a pre-terminal condition induced by massive hemorrhage, timely treatment with TRH-T will restore heart and brain perfusion to levels compatible with survival and with functional recovery from ischemia and maintain it at those levels for some hours
